Quadrilaterals
Chapter Outline

6.1 Angles in Polygons

6.2 PROPERTIES OFPARALLELOGRAMS

6.3 PROVINGQUADRILATERALS AREPARALLELOGRAMS

6.4 RECTANGLES, RHOMBUSES ANDSQUARES

6.5 TRAPEZOIDS ANDKITES

6.6 CHAPTER6 REVIEW

This chapter starts with the properties of polygons and narrows to focus on quadrilaterals. We will study several
different types of quadrilaterals: parallelograms, rhombi, rectangles, squares, kites and trapezoids. Then, we will
prove that different types of quadrilaterals are parallelograms or something more specific.
